The Boleti are fleshy fungi, readily undergoing decay like the fleshy agarics. 
They possess a cap and stem but the spore-bearing surface, instead of covering 
the surface of gills, lines a series of tubes which are readilv separable from the 
substance of the pileus. Several species are common after autumn and winter 
rains.
